(01.. 88-53) This i'nvention :relates to ophthalmic frames and. mountings, more I particularly. to temples, temple connections vandweyewzire :screwsh j in 11's an object of this invention to prevent, temples on ophthalmic .frames .:.and :mountings from becoming loose and wobbly as they: be- I come wornwfromtuse.

It is also an objectiof this inventioneto provide a novel structure lwhereinfthe eyewire .screw offlophthalmic rframes andlmountings can .be

locked in place. I I j I It isa further object ,of thiswinvention by its novel structure to presenta more harmonious endpiece for ophthalmic frames and mountings.

.It is aimedtoprovidea; novel structure .wherein the temple may be held in various. positions even I after lengthy use, solely by friction, and more wire screw for endpiece of the frame eyewires;

Figure 8 is a detail perspective view showing mounting for rimless glasses;

specificallyzthroughcompression of an expansible end portion, which is thereby tensioned, and coacts with parts of an ophthalmic frame or" mounting.

J Ihe more specific objects and advantages will become apparent from a consideration of the description following taken in connection with the accompanying drawing illustrating an operative embodiment.

In said drawing: i I

Figure 1 is a plan view showing the temple mounted in the endpiece of a frame;

Figure 2 is a detail section taken on the line 2-2 of Figure 1;

Figure 3. is a detail section taken on the line 3-.3-of Figure l;

Figure 4 is a horizontal section through the endpiece of the eyewires;

Figure 5 is a detail view showing the end portions of the temple expanded, also the square projection on the outside portion;

Figure 6 is a detail perspectiveview of the frame showing the endpieces of the eyewire together; e v

Figure 7 is a detail perspective view of the eyea modified form of an endpiece as used on a I on a mounting for rimless glasses.

Figure is a detail perspective view of the other side of the endpiece shown in Figure 9; and

tion of a modified form of temple.

Referring specifically to the drawing and first 1 Figure .11 is a detail plan view of one end pore interengage another form of jaws with a pointed to the'iform .of Figures :1 lto, '1, each gtemple Itll employed for.useiniophthalmicirames or mountings has one endrsplit as at IL-whereby: ex-

panding portions I2 are provided, uheing unrestrictediinithe condition showndn Figure 5'.

SuchrportionsJ-above. and below itheitemple proper have semi-circular tenon portions I3, the outor attached thereto as preferred.

Associated with I each lensof [the glass. or spec tacle designated I4. areseparable eyewires I5 and I6. In the form of the invention shownin Figuresl to 7, such-eyewires form part. of the frame II, which surrounds the lenses I4 and which aremsplit intermediate said eyewires I5 and I6,

which are continuations of the opposite ends of such frame Il. Said eyewires I5 and I6 have I sockets as at I8 in which the tenon portions. I3

are disposed, it being necessary to move such tenon portions I3 into contact in order to occupy the sockets I 8. As a result, the split portions I2 are placed under tension and tenon portions l3 will always frictionally engage the peripheral walls of the recesses where the eyewires come together, and this frictional actionwill be maintained throughout the life of the temples and ophthalmic frames or mountings as a whole. No

screws, or other extraneous fastenings, are therefore necessary in connection with the mountin of the temples.

In order to hold the eyewires I5 and I I6 together, a screw member I9 passes through one of them and. is screw threaded as at in the other. Such screw I9 has a head 2I journaled in the eyewire I6 and to prevent its loosening or self-displacement a set screw 22 is threaded through the rear of the eyewire at the endpiece and engages a threaded gear similar to a worm gear at 23 in the periphery of the head 2|.

In the modified forms of Figures 8 to 11, the

same principle and construction as in the preceding form is followed for the connection of the temple to the endpiece. In this form of the invention, the lens 14' does not have a surrounding frame like that at I1. jaws l5 and I6 functioning like the eyewires at I5 and I6, and which are securedv in any I suitable manner as at 24, to the lens I4. Such out sloping portion as at 25, and also shown to The tenon It does have jaws I5 and I6 interengage at a pointed cutand straight cut-out portion as shown in Figures 9 and 10. Such jaws have recesses or sockets as at l8 and the same may be engaged by the tenon portions I 3 of the temple ID or they may be engaged by the modified form of temple shown in Figure 11. This modified form of temple has portions I2, normally expanded away from each other and extending from a temple as at l0.

Such portions l2 are separatedby an expansive leaf springsuch as 26, located in arecess 21 between the portions 12,. Such portions at top and bottom have tenon portions l3, correspond-, ing to and functioning like those at l3.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

,1. In a mounting of the class described, lensmounting jaws, a temple split inwardly from one end providing portions normally urged away from each other at the outer end of the temple,

tenon portionsextending. from opposite sides of said .portionsintersected by the split, said jaws being separable on a line intersecting said split and havingsocket's'extending from opposite sides of said line, said sockets being of 'less diameter than the normal diameter of the associatedtenon portions, said tenon portionsbeing engaged in said sockets when said first mentioned portions are compressed toward ea'ch'other, so that the tenon portions will be expansive in the sockets, and .means separably connecting the jaws together.

extending inwardly beyond the tenon portions,

said jaws being separable ona line intersecting said split and having sockets extending from opposite sidesv of said line, said sockets being of less diameter than the normal diameter of the associated tenon portions, said tenon portions being engaged in said sockets when said first mentioned portions are compressed toward each other, so that the tenon portions will be expansive in the sockets, and means separably connecting the jaws together, one of the first mentioned portions at the split having a recess,

and spring means within the recess abutting the opposed first mentioned portion and urging separation of said first, mentioned portions.

3. In a mountingo'f the class described, lensmounting jaws, a temple split inwardly from one end providing portions normally nrged away from each'othe'r at the outer end of thetemple, tenon'portions extending from opposite sidesof said portions intersected by the split','-'said split extending: inwardly beyond the tenonportions, said jaws bein-g separable on a line intersecting opposite sides of said'lin'e, said--sock'etsbeing of less diameter than the normal diameter of the associated tenon portions, said tenon portions being engaged in said sockets when 'saidfirst mentioned portions: are compressed toward each other, so that theitenon portions will be'expan sive in the sockets, and means separably'connecting the jawstogethen' and a shoulder at the outer extremity of one of said 'portionsintermediate the tenon portions thereof engageable with one of the end pieces" to limit the swinging movement of the temple;v
